Snake River and South Fork settle into fall trout rhythm
Early October marks the shift into fall rhythm on the Snake River and South Fork, as cooling water typically pulls trout into more active feeding windows after the slower pace of late summer. Trout Unlimited's ongoing work on the Snake River basin this month centers on salmon and steelhead recovery advocacy for the lower river, a reminder that this stretch remains core salmonid water heading into the colder months.
Snake River steelhead run tracking toward a historic low
This year's Columbia and Snake River steelhead migration is shaping up to be the smallest ever recorded, according to Hatch Magazine, which reports fisheries managers have tallied just over 52,000 fish above Bonneville Dam since counting began July 1. Trout Unlimited is treating the numbers as further evidence for its long-running push for a free-flowing lower Snake River, framing this season as the latest data point in a recovery effort it has tracked for years. For anglers working the Snake and Salmon systems this fall, that headline number matters more than any single technique: there are simply fewer fish moving through the system than usual.
Snake River steelhead run the smallest on record this fall
Hatch Magazine reports the 2026 Columbia and Snake river steelhead run is the smallest ever recorded, with fisheries managers tallying just over 52,000 fish above Bonneville Dam since counting began July 1. Our read is that Snake steelhead fishing is in a slow, low-abundance year. Trout Unlimited's Snake Week films make the same point from the riverbank, framing the loss of salmon and steelhead as a basin-wide problem for anglers, families and communities.
Snake River run counts hit record low as fall sets in
Hatch Magazine reports the 2026 Columbia and Snake river run is the smallest ever recorded, with just over 52,000 fish tallied above Bonneville Dam since counting began July 1. Expect a thin fall return across the system, and plan trips around the water that is holding fish rather than around the numbers you hoped for.
Snake River steelhead run hits record low as fall push continues
The Snake River's steelhead run is shaping up to be the smallest ever recorded, according to Hatch Magazine. Fisheries managers have tallied just over 52,000 fish past Bonneville Dam since counts began July 1, putting 2026 well behind any prior year on record. For anglers planning fall steelhead trips on the Snake, that means fewer fish moving through and tighter windows to connect. Elsewhere in the state, Field & Stream reported a Montana angler landing a potential world-record-class smallmouth bass in an Idaho lake on a homemade glide bait, worked through deep structure off a point that drops from shallow water to over 100 feet, a reminder that smallmouth are keying on structure transitions this time of year.
Snake River steelhead run tracks toward historic low this fall
This fall's steelhead push into the Snake River system is shaping up as one of the thinnest on record. Hatch Magazine reports that combined Columbia and Snake river steelhead counts at Bonneville Dam, where tallying began July 1, have reached just over 52,000 fish, making the 2026 migration the smallest ever recorded there. For anglers working Idaho's Snake and Salmon River drainages this fall, that scarcity is the story to plan around: fish are still moving upriver, but the overall numbers reaching Idaho water this year are well below a typical season.
Historic-low steelhead run trickles into the Snake River this fall
This year's Snake River steelhead run is shaping up to be the smallest ever recorded, Hatch Magazine reports, with fisheries managers counting just over 52,000 fish above Bonneville Dam since tallies began July 1 — a steep drop from typical fall Columbia-Snake system migrations. For anglers working the South Fork and mainstem this week, that means fewer fish moving through than a normal fall run, and success will lean more on persistence and reading water than on timing a big push of fish.
Snake & Salmon steelhead run at record lows as water cools into fall
USGS gauges across the Snake and Salmon system are reading 56 to 62°F this week, with the larger reaches running 3,200-3,280 cfs and the smaller water down at 1,350 cfs, a clean fall thermal split across the basin. The headline for anyone targeting steelhead is sobering: per Hatch Magazine, this year's Columbia and Snake River steelhead run is on pace to be the smallest ever recorded, with just over 52,000 fish tallied above Bonneville Dam since counting began July 1. That run has been building slowly all summer and remains well off historical pace, so steelhead water that would normally be turning on with the first real cool-down is still fishing slow this week.
South Fork brown trout begin fall staging as flows ease
Water in the South Fork corridor is running elevated for late September, per the USGS gauge tracking this stretch of the Snake River system, with autumn's cooling trend just beginning to take hold. Hatch Magazine's coverage this month put a number on what's happening system-wide: the 2026 Snake and Columbia steelhead run, counted at Bonneville Dam since July 1, is tracking as the smallest on record — a signal worth keeping in mind for anyone fishing anadromous water downstream, even if resident trout in the upper drainage aren't directly affected.
Snake River steelhead run arrives at historic lows
This year's Columbia and Snake river steelhead run is on pace to be the smallest ever recorded, per Hatch Magazine, with fisheries managers counting just over 52,000 fish past Bonneville Dam since tallies began July 1. For anglers working Idaho's Snake and Salmon systems, that number matters more than any single day's weather — it means fewer fish moving upstream into these waters this season, and it's the dominant factor shaping what to expect on the water right now.
Snake River steelhead run reported at record lows this fall
Hatch Magazine reports that this year's Columbia and Snake River steelhead run is tracking as the smallest ever recorded, with only about 52,000 fish tallied above Bonneville Dam since counting began July 1. That's the number anglers working the Snake River and South Fork stretches in Idaho need to know this week: fewer fish are moving through than in a typical fall, so plan around patience and cover water methodically rather than expecting steady action.
Snake River steelhead run tracks toward record lows
USGS gauges across the Snake River system read 58°F at solid late-summer flows of 4,470 cfs (site 13341050) and 4,400 cfs (site 13342500) this morning, while a smaller feeder gauge (13340000) is running warmer at 67°F on 2,310 cfs. Those readings frame a bigger story: Hatch Magazine reports the 2026 Columbia and Snake steelhead run is shaping up as the smallest ever recorded, with just over 52,000 fish tallied above Bonneville Dam since counting began July 1.
Fishing in Idaho
Idaho might be the most underrated trout state in the country. The Henrys Fork is on every serious fly angler's list, the Salmon River carries steelhead hundreds of miles inland from the ocean, and the South Fork of the Snake grows big cutthroats and browns through spectacular canyon country. Up north, Lake Coeur d'Alene and the panhandle lakes add pike, bass, and kokanee to the mix.
When to fish Idaho
The spring steelhead season winds up on the Salmon and Clearwater drainages while the trout rivers swell with runoff. Pre-runoff windows and the tailwaters keep trout anglers busy, and the panhandle lakes wake up for pike and bass.
This is when Idaho shines: legendary hatches on the Henrys Fork, cutthroats eating dries on the South Fork of the Snake, and high mountain lakes open for backpacking anglers. Kokanee and trout trolling holds strong on the big northern lakes.
Fresh steelhead push up the Salmon and Clearwater in the fall run that Idaho is famous for. On the trout rivers, brown trout turn aggressive before the spawn and the cottonwoods go gold over empty water.
Steelhead fishing continues through the cold months for anglers willing to bundle up, and the tailwater sections keep trout feeding on slow, deep presentations. Ice fishing takes over the panhandle lakes for perch, kokanee, and trout.

Common questions
Do I need a license to fish in Idaho?
Yes, a fishing license is required for most anglers, with additional permits for steelhead and salmon. Idaho Fish & Game sells everything online, and season rules vary by river and run, so check the current regulations before you go.
What fish can I catch in Idaho?
Trout headline the state: rainbows, browns, brookies, and native cutthroats across the famous rivers, plus ocean-run steelhead and chinook salmon that travel all the way up the Snake and Salmon drainages. The lakes add kokanee, pike, smallmouth, and perch.
When is the best time to fish Idaho?
Summer is prime for the classic dry-fly water once runoff drops, and fall doubles up with returning steelhead and aggressive brown trout. Spring steelhead and winter tailwater fishing round out a genuine year-round calendar.
